BORING- MAGHINE. 1

' Application filed January 16, 1923. Scrial No. 612,961.

T 0 all whom it may concern:

Be it known that 1, JOHN B. OWENS, a citizen of the United States, residing at Oleika, in the county of Bell, State of Kentucky, have invented a new and useful Boring Machine; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to boring machines, and has for its object to provide a boring machine for driving a coal auger manually and quickly. Also to provide a supporting base for the drilling machine, which supporting base is provided with wheels whereby the machine as a whole may be easily moved from place to place.

A further object is to provide the drill ing machine with a breast plate adapted to engage the breast of the operator and w th double cranks having gear connections with the auger, thereby allowing the operator to use both hands in operating the machine,

' and consequently imparting a greater power on the driving mechanism.

A further object is to pivotally mount the machine on the supporting base, and to provide the machine with a pivoted segmentallyshaped member having teeth cooperating with a lug on the base for holding the machine at various angles.

WVith the above and other objects in view the invention resides in the combination and arrangement of parts as hereinafter set forth, shown in the drawing, described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of. what is claimed without departing from the spirit of the invention.

In the drawing Figure 1 is a side elevation of the machine, parts being broken away to better show the structure.

Figure 2 is a top plan View of the machine.

Referring to the drawing, the numeral 1 designates the casing of the drilling machine, which casing is formed from asso ciated sections, preferably riveted together at 2. Disposed within the casing 1 and rotatably mounted in bearings thereof is a transversely disposed shaft 3, which shaft is provided with a bevelled gear 4, which meshes with the bevelled gear 5 of the drive shaft 6. The drive shaftG rotates a conven- I tional form of chuck 7, in which the coal boring auger 8 is held. Mounted on'the shaft 3 is a pinion 9, with which pinion 9 a large drive gear 10 meshes. The gear 10 is carried .by a transversely disposed shaft 11, which shaft is provided with operating cranks 12 at its ends, which cranks are disposed outside of the casing 1 and extend in opposite directions but are in the same lane, thereby allowing the operator of the drilling machine, when the breast" plate 13 is in engagement with his breast, to grasp both of the operating cranks 12 and rotate the drive gear 10 with both hands, consequently obtaining a maximum amount of power and allowing the operator to utilize both hands in operating the machine.

Casing 1 is pivotally connected at 14 to a supporting base 15, the lower ends of which base are provided with wheels 16,

whereby the machine as a whole may be easily and quickly moved from place to place, and at the same time the machine supported during the drilling operation. However to maintain the drilling machine in various angles during a drilling operation, a segmentally shaped arm 17 is provided, which arm is pivotally connected at 18 to the casing 1 and is provided with a plurality of teeth 19, which teeth cooperate with a lug carried by the base 15 for hold ing the casing 1 in any position to which it may be moved in avertical plane. \Vhen the operator desires to release the segmentally shaped member 17, it will be seen that it will only be necessary for him to raise the segmentally shaped member 13 with his foot or hand as desired.

From the above it will be seen that a boring machine is provided, which is particularly adapted for boring holes during a coal mining operation, and one wherein the drilling auger isrotated through a gear train, which gear train is operated by a multiple of cranks, thereby obtaining the maximum amount of power. It will also be seen that the drilling machine may be moved and held at various angles during the drilling operation and that the device may be easily and quickly moved from place to place.

The invention having been set forth what is claimed as new and useful is The combination with a coal mine drilling machine comprising a casing having a breast plate at one end thereof, an axially alined driving shaft at the forward end of the casing and rotatably mounted in bearings therein, of a gear train and operating mechanism for said drive shaft, said mechanism comprising a transversely disposed drive shaft extending through the casing,

.a transversely disposed counter shaft eX- tending through the casing in parallel relation to the transversely disposed drive shaft, meshing gears carried by said transversely disposed shafts in the same plane as the longitudinal center line of the casing,
